These days, I am enjoying FPS solo and coop play much more than multiplayer, because I don't like the way game studios are using algorithms to screw around with gameplay, random gun nerfing, purposely matching certain weapons to other weapons, SBMM, etc. For example, the latest CoD is a very different game now from when it was first released. You can feel how the game is being manipulated, to keep people playing and thinking they can just tweek some setting or other, here and there, or keep trying different guns, and get their K/D ratio back up. I want to play a game where my skill determines whether or not I win--not some algorithm giving me an edge in one match, and then screwing me in another. I hope that offline bot play will allow you to level up, also. That would be the icing on the cake--and I would gladly put my money down for each new BF version, if it included that.
